Problem : Fast Busies New Hampshire MegaPOP Location: 089 - New Hampshire, NH Status : Ongoing Event : Major problem with DialUp We are currently experiencing fast busies at this location due to an SS7 outage of our providers. They are currently working to resolve the issue as quickly as possible, however there is no ETR. Further updates will be posetd as warranted. 'SS7' is a digital network used for signalling between telephone company central offices, or between the central office and customer equipment. If it is "down" then the central offices can't communicate which effectively renders call processing impossible.
